Deistertag Barsinghausen

17th Deistertag on Mother's Day 2026

The Deister, with its approximately 26 km length and forested heights, is the largest contiguous forest area in the south of the Hannover region. Barsinghausen, located on the northern slope, is uniquely connected to the Deister – historically through mining, today through tourism, sports, and recreation. The Deistertag celebrates this connection annually with a family-friendly festival day.

Klosterstollen Show Mine

The heart of the festival is the Klosterstollen show mine. Here, visitors can immerse themselves in the world of historical hard coal mining – through guided tours, exhibitions, and an authentic tunnel system. The Klosterstollen is one of the most important technical monuments in the region and is open on Deistertag from 10 am to 5 pm.
